Sienna Miller keen to act with beau in flick?

London, Dec 2 : Hollywood actress Sienna Miller is keen to act with 'beau' Balthazar Getty in a flick and the two are looking for a suitable project, according to sources.

However, the Sienna's entourage feel that the pair would be as unpopular on screen as they are off it.

"Her advisers are warning how unpopular that would be. People haven't taken to them as a pair due to the way they got together. They fear people will find it a bit too sickly - and as though they are rubbing his wife's face in it," The Sun quoted a source, as saying.

"But Sienna insists it could be movie gold and is looking for a script," the source added.

Balthazar's estranged wife Rosetta Millington, who is a mother to his four kids - was humiliated in the summer when photos emerged of her hubby and Sienna frolicking on a boat.
